Embodiment 1

[0048] Such as figure 1 As shown, the present invention discloses an electronic equipment monitoring device based on a subway monitoring system, including a sound source acquisition preprocessing system, a human voice and non-human voice recognition system, a sound source recognition system and a recognition result processing system, wherein:

[0049] The sound source collection preprocessing system is used for real-time collection and preprocessing of multi-source sound complex signals in subway cars including human voice and non-human voice;

[0050] The human voice non-human voice recognition system is used to identify and decode the multi-source complex signals in the sound source through the human voice acoustic model in combination with the language model, and specify the type of non-human voice signal (such as the subway buzzer sound signal) ) is transformed into a custom output, and human voice signal recognition triggers the next-level sound source recognition system;...

Embodiment 2

[0069] Such as figure 2 As shown, the present invention additionally discloses a monitoring method for electronic equipment based on the subway monitoring system, using the above-mentioned electronic equipment monitoring device based on the subway monitoring system for monitoring, including the following steps:

[0070] Step 1: Collect the noise audio signal of the subway car, and preprocess the real-time collected multi-source sound complex signal of the subway car including human voice and non-human voice;

[0071] Step 2: Separate the human and non-human voices from the multi-source complex signals in the sound source, and convert the specified type of non-human voice signals (such as the subway buzzer sound signal) into a custom output, and trigger the human voice signal recognition Level 1 sound source identification system;

[0072] Step 3: Establish an audio feature library that includes train station announcement broadcast signals and OCC (subway operation control ce...

Abstract

The invention discloses an electronic equipment loudspeaker monitoring device and monitoring method based on a subway monitoring system, and the device comprises a sound source collection and preprocessing system, a human voice and non-human voice recognition system, a sound source recognition system, and a recognition result processing system. The sound source collection and preprocessing system is used for collecting subway carriage multi-source sound complex signals possibly including human voice and non-human voice in real time and preprocessing the subway carriage multi-source sound complex signals; the human voice and non-human voice recognition system is used for recognizing and decoding through a human voice acoustic model in combination with a language model so as to separate multi-source complex signals in the sound source; the sound source recognition system is used for converting the sound signal into a spectrogram to carry out spectrogram saliency detection so as to judge and eliminate train station announcement broadcast and OCC broadcast audio frequency and output a preliminary audio frequency type judgment result; and the recognition result processing system is used for receiving the recognition result preliminarily judged by the sound source recognition system and linking the subway multi-monitoring system to perform specified operation according to different results.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to an electronic equipment monitoring device and monitoring method based on a subway monitoring system. Background technique [0002] Rail transit has become an important choice for more and more citizens to commute daily. From December 1, 2020, the newly revised "Shanghai Rail Transit Passenger Regulations" will be officially implemented, which adds a prohibition on the sound of electronic devices such as mobile phones, tablets, and smart watches. The existing supervision scheme usually relies on the subway staff to manually board the train for inspection, but especially for places with a large flow of people and a high density of people on the train, there are many difficulties in supervision. . [0003] As we all know, loud noises are prohibited in public places. If the circumstances are serious, disturbing public order, hindering public safety, or violating the rights of othe...
